| 摘 要： | 材料力学中推导矩形剖面横力弯曲剪应力公式时，是以儒拉夫斯基假设为基础的．但儒拉夫斯基假设并非在所有的矩形剖面梁中都能应用，只有在狭矩形梁中应用才是正确的．本文将讨论为什么只有狭矩形梁中儒拉夫斯基假设是正确的，狭矩形梁狭到什么程度该假设才是正确的，并给出计算机数字计算结果及图表．

| Abstract: | The deduction of the shearing stress formula of rectangular-section beams laterally loadedis based on Jourawski's hypotheses. But the hypotheses can not apply in all the rectangular-section-beams except in the narrow beams. This paper explains why they are applicable in narrow beams andfurthemore,give results and charts worked out by computer. |
